Document Summary

Foot muscle: muscles are more massive than upper limb. Lateral rotators: all muscles originate on hipbone and insert on femur, all move hip joint sacral plexus: innervates muscles, gluteal muscles gluteus maximus: most superficial, hip extensor gluteus medius: medial rotator gluteus minimus: deepest, medial rotator. Make up buttocks, very powerful muscles: 6 lateral rotators: muscles that laterally rotate hip. Anterior (extensors): extend the knee (quadriceps innervated by femoral nerve) Lecture #11 - lower limb muscles: sartorius: longest muscle in the body, originates on hip bone at anterior superior illiac spine, inserts on proximal tibia, quadriceps femoris: insert on patella. Rectus femoris -> originates at anterior inferior illiac spine. Vastus intermedius -> deep to rectus femoris, originate on femur. Medial (adductors): adduct the thigh (innervated by obturator nerve), originate on pubis all insert on medial aspect of femur, except for gracilis (proximal tibia)
